Jobbnorge ID: 170296

About the position

A fixed-term 100 % position is available at the University of Agder, Faculty of Engineering and Science, as a Post-doctoral Research Fellow in Information and Communication Technology, for a period of 2 years. The position is located, at the present, at the Campus Grimstad. The starting date is as soon as possible or to be negotiated with the Faculty.

The Postdoctoral researcher will be supervised by researchers from the Center Intelligent Signal Processing and Wireless Networks (WISENET), Faculty of Engineering and Science, UiA. Information about why UiA provides an excellent working environment can be found here.

This postdoctoral researcher position is offered in the area of Testbed design (hardware and software) and experimental evaluation for reproducible research, covering scenarios related to distributed networked sensor systems for industrial environments, as well as future Artificial Intelligence-enabled advanced wireless networks.

The herein announced position will be part of the Center Intelligent Signal Processing & Wireless Networks (WISENET), whose activities span across both the Department of Information and Communication Technology and the Department of Engineering. The WISENET Center is recognized and funded by the national NFR TOPPFORSK Programme, Research Council of Norway. The WISENET Center has a strong expertise in a wide range of areas, among them, Data Analytics, Machine Learning, In-Network Processing and Distributed Intelligence, Networked Cyber-Physical Systems, Artificial Intelligence for Wireless Networks and Embedded Systems, having led a number of large research projects, funded by the Research Council of Norway, the EU research Programmes FP7 and H2020, as well as national and international industries. The WISENET Center is now in full expansion phase, having at the present ten PhD students, three postdoctoral researchers, working on different cutting-edge research projects, such as FRIPRO FRINATEK, SFI, PETROMAKS, INFRASTRUCTURE and IKTPLUSS Projects, among others. The WISENET Center is committed to achieving international research excellence; please see the notes about prospective Postdoctoral researchers at WISENET before applying.

A postdoctoral research position should function as an intermediate step in the research career following the completion of a PhD degree and preceding a faculty position in a university. For this reason, the WISENET Center is committed to offering the suitable environment and activities that allow the postdoctoral researcher to (i) consolidate her/his research maturity, (ii) develop her/his teaching and advising skills, and (iii) build up a solid resume that facilitates her/his incorporation to the academia as an assistant or associate professor.

Responsibilities

The new demanding applications in different domains (smart sensing and controlling systems remotely, remote monitoring of environments, machine learning for industrial applications, distributed intelligence in Industry 4.0, IoT, Artificial Intelligence-enabled unmanned aerial vehicles, computer vision for autonomous drones, video analytics for autonomous traffic management, etc...) require the design of novel and heterogeneous Wireless Sensor and Communication Networks composed of various types of nodes with different local processing and wireless communication capabilities, diverse sensing and actuation functionalities.

Experiments in wireless sensor and communication networking are of paramount importance since the scientific community has not reached a consensus on a reference model due to the extremely large number of parameters to be considered. As a consequence, the gap between simulation and experimentation may lead to significant differences between the performance of the simulated system and that of the real system. Most of the existing Testbeds dedicated to wireless sensor and communication assessments are composed of homogeneous devices. They are built using mature technologies, however, the experimental validation of the transmission, sensor and networking techniques that are developed in the theoretical research works, requires the construction of a Testbed made up of heterogeneous nodes not only devoted to transmission, acquisition and processing of wireless signals, but also to spectrum, context-aware sensing and node positioning.

This postdoctoral position will involve the complete design and detailed evaluation of a novel Testbed, which will be composed of devices having wireless re-programming capabilities, as well as a complete software architecture and protocol stack to maximize the reproducibility of Algorithms and Protocols for research. This Testbed will also include both indoor and outdoor nodes with proper packaging and protection for robust operation in hostile terrain, corrosive environments or inclement weather.

The two key elements of our Testbed will be: a highly customizable and flexible hardware and software infrastructure to interconnect, configure, control and monitor all Testbed nodes, as well as an efficient, flexible and powerful software architecture to enable high-level and homogeneous access to each element of the Testbed (nodes, sensors, servers and services). Our Testbed will serve also as a platform (based on completely realistic measurements) for experimentation and to evaluate extensively some of the algorithms and networking techniques developed in several projects led by the WISENET Center.

In terms of tasks related to spectrum sensing, environmental sensing or energy harvesting, we will always use state-of-the-art hardware modules and develop highly efficient customizable wireless nodes (e.g. transceiver nodes based on state of the art FPGAs [Field Programmable Gate s] or GPUs [Graphics Processing Units]) and various types of nodes according to the performance needs in different scenarios. The planned wireless nodes will be specifically tailored to meet the ambitious goals in terms of minimal hardware complexity, low processing delay, lower power dissipation, energy efficiency, energy harvesting and re-programmability.

In order to extract information from the physical world and make it accessible remotely, different types of devices will be used. Although the majority of these devices will be low-cost and low-power devices, other nodes with higher capabilities will be also used. The low-cost devices, generally devices with low-computational resources (e.g. LoRa nodes), will be in charge of sensing the environment and performing some low-level computation. The devices with higher capabilities (e.g. USRP, NUTAQ platforms) will be in charge of more complex tasks, such as node coordination, data aggregation, more complex distributed signal processing tasks and machine learning algorithms, among others. All this hardware heterogeneity leads to the necessity of several research tasks of software design, integration and validation in order to achieve a full operative platform. For example, different devices may present different radio models and communication protocols, which may require developing new interfaces and drivers.

The hardware infrastructure will be composed of the following types of nodes:

• High-performance nodes with real-time processing capabilities (e.g. NUTAQ nodes).
• Medium-performance nodes (e.g. USRP nodes) with limited transmission and limited real-time signal processing capabilities.
• Sensor and actuator nodes (e.g. LoRA nodes) capable of gathering information from the environment, which can perform some local processing and communicate with other nodes in the network. The choice of sensors and actuators will depend on the applications considered (e.g. smart water networks, autonomous vehicles, smart agriculture, robotic applications, etc.).

The main topics for this Postdoctoral position will be:

• Design of a novel heterogeneous Testbed, implementation of advanced algorithms and extensive experimental evaluation. While the software architecture viewed as a whole will be the same for all testbed elements, each particular element of the heterogeneous network will have a different implementation of the lower-level layers constituting the software architecture.
• Development of novel network and software architectures for the experimental evaluation of communication and sensor networking techniques. This will involve also investigating the design of Software-Defined-Radio platforms that are capable of operating simultaneously with multiple wireless standards.
